Effect of using two dimensional code Laser marking machine for PCB

The advantages of two-dimensional code Laser marking machine in the PCB industry are fully reflected. The two-dimensional code with good quality, high efficiency, long-lasting marking, high consistency, low cost, safety and reliability is widely used. With the continuous development of smart phone technology and wearable electronic technology, intellectualization, thinness and miniaturization become the mainstream, and consumers' requirements for product quality will be higher and higher. How about the effect of two-dimensional code Laser marking machine in the processing field?

 

So how to realize the quality control of PCB, it needs to use the product quality traceability system. The commonly used method is to mark string, one-dimensional code, two-dimensional code and other information on the PCB board through laser marking technology, upload them to the database through camera identification, automatically eliminate unqualified products, realize the product quality traceability of the whole internal process, track the whole process from the source supplier information to the product delivery data, and maximize the product quality, And effectively realize the control of automatic production of products.

 

With the development of light and miniaturization of electronic equipment, the format of PCB board is very small. In order to save the utilization of space, usually, the two-dimensional code marked on PCB board is very small, such as 2x2mm size two-dimensional code, and contains more than 20 characters. This kind of high-density, small format two-dimensional code marking can only be realized by PCB Laser marking machine technology.

 

Compared with ink-jet, PCB laser marking technology is more environmentally friendly and economical. The permanent mark will not be easily erased. The non-contact non-destructive marking will not damage the substrate. The processing precision is high. The small format can achieve 0.12x0.12mm 31 bit two-dimensional code laser marking. It has long service life, works continuously for more than hundreds of thousands of hours, and has fast processing efficiency. One two-dimensional code can be completed within 1 second, The mark is exquisite, the hand touch is not obvious on it, the manual operation is simple, and the fool type processing.

 

Comparing the advantages and disadvantages of laser marking technology with ink-jet technology, we can see that when the new generation of PCB two-dimensional code marking is combined with laser technology, it will become a perfect partner. PCB Laser marking machine helps the PCB industry to complete the perfect quality control. The broad PCB market provides a broad development space for the Laser marking machine industry.
